Cessna Citation Longitude

Updated: October 2026 – A large, slim white jet stands on the general aviation apron: two mighty engines on the rear fuselage, the horizontal stabilizer right on top of the fin, the wings swept strongly back. At first glance it could be a Challenger. But if the Citation titles are on the fuselage and tracking shows the code C700, you are looking at a Cessna Citation Longitude – Cessna’s super-midsize jet and the largest Citation being built as of October 2026. Here you will learn how the Longitude came about, what sets it apart technically and how to reliably tell it from the Latitude, Challenger 350 and others.

What is the Cessna Citation Longitude?

Internally the Longitude carries the designation Model 700 and is the flagship of the current Citation lineup. It plays in the so-called super-midsize segment, that is, above classic midsize jets like the Citation XLS or the Citation Latitude, but below the large long-range business jets. The manufacturer today is Textron Aviation, under whose roof Cessna continues as a brand.

The road to the production aircraft was long. Cessna first presented the project in May 2012 at the business aviation trade show EBACE in Geneva. Back then a different engine was planned, the Safran Silvercrest; in production, however, the Longitude flies with Honeywell engines. The first flight took place on October 8, 2016 in Wichita. After a test program of about 6,000 flight hours, the US aviation authority FAA granted type certification on September 21, 2019. Deliveries began in fall 2019; the fractional ownership provider NetJets took delivery of its first Longitude on December 31, 2019. European certification by EASA followed in July 2021, and in May 2023 Textron delivered the 100th Longitude.

Technically the Longitude builds on the Latitude: the fuselage cross-section is identical, but the cabin is stretched by one seat row. Everything else is new – wing, tail and engines differ clearly from the smaller sibling. That is exactly what makes the two easy for spotters to tell apart, even though their fuselages are so similar.

The Longitude is powered by two Honeywell HTF7700L engines with about 34 kN of thrust each. According to the current data sheet it reaches a cruise speed of up to 483 knots, may fly up to Mach 0.84 and climbs to as high as 45,000 feet. Cessna gives the range as up to 3,500 nautical miles – enough for many transatlantic routes. How far it actually goes in everyday use depends, as always, on payload, wind and reserves.

According to the manufacturer, the cabin measures about 7.67 meters in length, 1.96 meters in width and 1.83 meters in height; adults can therefore stand upright in it. Up to twelve occupants are possible. The baggage compartment is accessible from the cabin in flight. In the cockpit works the Garmin G5000 with touchscreen controls, and autothrottles are standard on board. Options include a head-up display with enhanced vision.

Origins: the Longitude in the Citation family tree

The Citation family is so large that it is easy to lose track. The Longitude sits at the very top of today’s lineup. The following table places it against its closest relatives.

Model	ICAO code	Tail	Wing sweep	Length
Citation CJ4	C25C	T-tail	12.5°	16.26 m
Citation Latitude	C68A	cruciform tail	16.3°	19.0 m
Citation Longitude	C700	T-tail	28.6°	22.3 m

The Citation Sovereign (C680) is another midsize Citation with a cruciform tail, while the fast Citation X (C750), like the Longitude, has a T-tail and an even more strongly swept wing. The Citation X is, however, a separate, older design with a narrower fuselage. Cessna was also already working on a larger sister, the Citation Hemisphere; Textron suspended its development in 2019, though, because the intended engine missed its targets.

The three features that are enough to identify it

In the super-midsize segment many jets look alike: two engines on the rear fuselage, swept wing, slim fuselage. For the Longitude, three observations help you.

In the end the registration confirms the type. You use it to look the aircraft up in registry databases and see the year of manufacture and owner. How registrations are structured is explained in the post Understanding aircraft registrations. Which code belongs to which type is shown in the article on ICAO type codes.

Longitude or Latitude?

The most common mix-up happens within the family itself. Both jets stand on the same aprons, especially with fleet operators like NetJets that use both types.

Feature	Longitude	Latitude
Official designation	Model 700	Model 680A
ICAO type designator	C700	C68A
Tail	T-tail	cruciform tail
Wing sweep	28.6°	16.3°
Length	22.3 m	19.0 m
Wingspan	21.01 m	22.05 m
Engines	2 × Honeywell HTF7700L	2 × P&WC PW306D1
Cabin length	7.67 m	6.63 m
Occupants max.	12	9

Remarkable: the smaller Latitude has the larger wingspan. Its less swept wing is designed broader, while the Longitude flies faster and farther with a shorter but more strongly swept wing. Cabin height and width, on the other hand, are the same on both – that is the shared fuselage cross-section.

Longitude, Challenger 350, G280 or Praetor 600?

Outside the Cessna family there are three super-midsize jets you should keep an eye on. All have a T-tail and rear-mounted engines. The finder helps you narrow it down.

The Bombardier Challenger 350 and its successor, the Challenger 3500, are the most direct competitors and are very widespread in Europe. At about 20.9 meters they are a bit shorter than the Longitude and carry distinctive, outward-canted winglets. The Gulfstream G280 gives itself away through its large oval windows. The Embraer Praetor 600 shows up in tracking as E550 and carries distinct winglets. For all of them, the silhouettes look very similar from a great distance, and a good photo or the type code settles it.

Where to find the Longitude

The Longitude flies for owners, companies, charter providers and fractional ownership programs. By far the best-known operator is NetJets: the provider ordered up to 175 aircraft in October 2018 and took delivery of the first at the end of 2019. The NetJets Longitudes fly mainly in the North American program. In Europe you therefore meet the Longitude mostly with private and charter operators or on transatlantic visits by US-registered aircraft. There are also special missions: since 2022 the Japanese aviation authority has used a Longitude to calibrate navigation aids.

Location	Chance of a catch	Why
Geneva	high	One of Europe’s most important business aviation airports, especially during trade fairs and conferences
Zurich	medium to high	Lots of business travel traffic, its own GA apron
Paris-Le Bourget	high	A pure business aviation airport, many transatlantic jets
Nice	high in summer	Heavy private jet traffic in season
Salzburg	medium, seasonal	Ski traffic in winter, festival season in summer

At Geneva Airport, from the observation deck you have good chances of business jets of all sizes; details about the spot are in the Geneva plane spotting guide. At Zurich Airport the Butzenbüel and the spectator terrace B are worth it; more in the Zurich plane spotting guide. A special case is Paris-Le Bourget Airport, which handles almost exclusively business aviation. In winter Salzburg Airport with its observation deck is a classic, in summer Nice Airport.

How to follow individual aircraft specifically is explained in the post Tracking an aircraft by registration. You will find general tips for hunting private jets in Spotting business jets and Spotting general aviation.

Spotting at the GA apron: how to plan your session

Business jets usually park on separate aprons away from the big terminals. For good pictures you therefore need a vantage point with a view of that apron or a spot on the approach path. The Longitude is big for a business jet, but at about 22 meters it is still much smaller than an A320. So plan for more focal length than for airliners.

Whether your vantage point is legally unproblematic is covered in the article Is plane spotting allowed?. Which lenses suit smaller aircraft is in the guide to the right focal length.

Common lookalikes and how to rule them out

Conclusion

The Citation Longitude is Cessna’s step into the super-midsize class: the Latitude’s fuselage cross-section, but stretched and with a T-tail, strongly swept wing and Honeywell engines. For spotters, that very combination is the ticket to a reliable identification. Telling it from the Challenger 350, G280 and Praetor 600 works through windows, winglets and titles – and when in doubt through type code and registration.
